Battery capacity

Battery capacity is the amount of charge it can store, expressed in mAh (milliamp-hours) or, sometimes, in Wh. At equal consumption, a larger capacity generally allows more running time, but the duration also depends on the motor and settings.

Why it matters: It does not coincide with runtime: two machines with the same capacity can last different times. Comparing batteries at different voltages requires Wh.
